fix(config): inline config intermingled

[grandizzy]

Motivation

inline config is not properly parsed when multiple tests in same file, for a file with 2 tests like

// SPDX-License-Identifier: MIT OR Apache-2.0
pragma solidity >=0.8.0;

import "ds-test/test.sol";

contract FuzzInlineConf is DSTest {
     /// forge-config: default.fuzz.runs = 1
    function testInlineConfFuzz1() {}
}

contract FuzzInlineConf2 is DSTest {
    /// forge-config: default.fuzz.runs = 2
    function testInlineConfFuzz2() {}
}

the natspec parsed for FuzzInlineConf2 is

{ 
  contract: "inline/FuzzInlineConf2.t.sol:FuzzInlineConf2",
  function: "testInlineConfFuzz2", line: "0:0:0",
  docs: "forge-config: default.fuzz.runs = 1\nforge-config: default.fuzz.runs = 2" 
}

instead

{ 
  contract: "inline/FuzzInlineConf2.t.sol:FuzzInlineConf2",
  function: "testInlineConfFuzz2", line: "0:0:0",
  docs: "forge-config: default.fuzz.runs = 2" 
}

This happens due to the fact that FuzzInlineConf2 is the 2nd source unit part but we parse from 0

Solution

parse natspecs from contract definition start location
